    Default The Aerial Friction Brake is here!

    The Aerial Friction Brake TS-1 is finally hitting the market, and we're really excited about it. The design is based off Carroll C. Bassett's BMS Belay Spool, and we made some changes to make it even better for arborists.

    Check it out, watch the video, let me know what you think.

    I highly recommend BixVid. It cures any ailment, prevents injury and reverses pre-mature baldness.

    Very nice, Nick! Excellent presentation. A lot of benefits in a tool like that. I will be getting one of these as, like you said, should be good for small 2 man (or person) crews.

    This is a very efficient tool.

    My concern while using the BMS Belay Spool for several years has been the rope bend radius. It seems to bend sharply at the corners. The corner radius seems like 1/2" or maybe 3/4". Can you weigh in on that? I would be interested to know if the rope bend is signicantly cutting the working capacity.

    The wider cheek plates are great. Should prevent the binding on a vertical stem...the largest drawback that I found with the BS.

    I wonder if the rope can jump over the roll pins that divide the rope turns during negative blocking. I thought that the pins were relatively longer on the BS, possibly too long to prevent the rope from hopping slots. Looks like they should/ could be longer to prevent this. If a negative blocked piece locks up due to the rope wrapping over itself, it will only have a very short section of rope (and sling and the tree) to absorb energy, possibly hitting the climber with the piece being caught. Maybe this is not an issue.

    I still don't think it'll beat a couple of cut stubs up the tree as a friction device.

    Pruning and spar work have no stubs.

    Predictable friction, a la a portawrap/ LD over trunk wraps.

    You can lower off of a keeper tree.

    Double-braid ropes don't like Natural Crotch rigging.

    That's what climbers will have to do if they don't have this tool.

    1. They can if you cut them in preparation.
    2. If it holds it it holds it, not everything has to run.(not talking about trunk wraps just holding it on stubs up the tree)
    3. .?
    4. As long as you're not running it, it'll last a long time, and if it needs replacing every few years so what?
    It's clever and everything, but it's just another thing to take up a tree that (under normal day to day circumstances) you can easily get around.

    Nick, it says 9/16" rope capacity. I know my BMS will barely handle 1/2" rope once it's "fuzzed" up a little. Is the 9/16" only when the rope is new, or is that allowing for some swell?
